A Fast method to predict the Voltage Droop for Fully Integrated Voltage Regulators in Microprocessors
2021 IEEE Electrical Design of Advanced Packaging and Systems (EDAPS)（2021）
摘要
Modern high performance server microprocessors processors have built-in Fully Integrated Voltage Regulators (FIVR) to generate the on-chip power domains. FIVR is designed using on-Die power MOSFETs, package inductors, on-Die capacitors, and feedback control circuits. High di/dt events on the output of FIVR domains lead to large voltage droops which affect the circuit performance. This voltage droo...
